Abstract
A vacuum insulating glazing unit is described. The vacuum insulating glazing unit has a first glass pane and a second glass pane; a set of discrete spacers positioned between the first and second glass panes, maintaining a distance between the first and the second glass panes; a hermetically bonding seal sealing the distance between the first and second glass panes over a perimeter thereof; an internal volume defined by the first and second glass panes and the set of discrete spacers and closed by the hermetically bonding seal, where the internal volume has an absolute vacuum pressure of less than 0.1 mbar; and an absolute difference between a coefficient of thermal expansion of the first glass pane and a coefficient of thermal expansion of the second glass pane is at most 0.40*10/° C.
